Kenchii Flipper 46-Tooth Professional Dog Grooming Thinning Shears - Perfect for Trimming & Thinning Pet Fur for a Smooth Finish

For the first 2-3 days I have had these they worked beautifully; loved them. Now they are unusable and I'm waiting to see if they can be fixed. One of the teeth catches and they wont open or close properly even with trying to reset the tension. There appears to be a burr on the blade side, I expected more after the reviews I read, they aren't cheap by any means. I also bought the 7 inch Flipper and I'm not impressed. you have to cut in the exact right spot of the shear or else they fold the hair. Again waiting to see if they can be sharpened and adjusted. I'm not dead set against Kenchii. I think had I bought from them direct I might have had a better experience, but right now I'm truly disappointed.They seem to cut okay but these are made for petite hands. The finger holes are about 19mm in diameter (~.75in). I have big hands and I couldn't get a good enough grip with my thumb to do a decent cut. I need clippers with at least a 26mm thumb hole.Kenchii is the only shear I use as a professional groomer. I love them!
